Adaptive Routing in Dynamic Ad-Hoc Network

The dynamics of an ad hoc network are a challenge to protocol design because mobility of nodes leads to unstable routing, and consequently flows encounter fluctuations in resource availability on various paths during the lifetime of a session. This has become serious, especially for those protocols based on single-path reservation, as frequent reservation and restoration of reservation-based flows increase the instability of connections. Advances in wireless research are focusing more and more on the adaptation capability of routing protocols. These protocols are interrelated to each other among various performance measures such as those related to topological changes (link breakages, node mobility, etc.) and Quality of Service (QoS) parameters (load, delay, etc). Sometimes, dynamic ad hoc networks resemble a dense ad hoc network.
